This study investigates the causal relationship between power energy consumption, FDI and Economic growth in Pakistan using time series data from 1965 to 2019. Johansen co-integration test is employed for finding out relationship and Granger causality test is used to find the direction of causality amongst the variables used. The results Granger test of causality finds unidirectional causality from FDI to GDP growth, a unidirectional causality relationship running from GDP growth toward power energy consumption and from foreign direct investment toward economic growth. Foreign Direct Investment has positive impact on the economic growth and economic growth stimulate energy consumption, so indirectly energy consumption is enhanced with the expansion of FDI, hence the government should pay full attentions to the security of foreign investors and enhance the energy production in order to enhance the economic growth of Pakistan.

Although coffee constitutes the largest share of exports, producers in Ethiopia have historically received a small percentage of the export revenue from the price of green coffee. Reasons often mentioned are heavy government intervention and high marketing and processing costs. Before 1992, government regulation of the domestic coffee market in the form of fixed producer prices and the Ethiopian Coffee Marketing Corporation's monopoly power put a substantial wedge between the producer price and the world price of coffee by imposing an implicit tax on producers. Having liberalized the market and adopted a floating exchange rate regime to boost exports (coffee) as the country struggles with foreign exchange shortages, not much has improved in exports (coffee) or foreign reserve availability. This paper utilizes monthly data from 2010-2015 to develop a multiple regression model to determine the impact the exchange rate has on coffee export if there is any. The empirical findings indicate that the exchange rate is not significant in determining or influencing exports but the prices of the two famous coffee types (Arabica and Robusta). Corroborated by the research outcome, we suggest that policymakers do not rely on the depreciation or devaluation of the ETB (Ethiopian Birr) as a tool for export promotion and growth.
